Yeah, it's kinda vague.
What it actually prohibits is "crossing one's legs on the neck...or other actions which may cause damage to the neck." I'm struggling to think what that might refer to. Is it a high guard? Or are they just concerned about the possibility of fighters who've learned to break necks with their legs, KGB-style?

Correct me if you read Cyrillic, but I'm pretty sure that rule says 1 point is awarded to any pair (team) that holds the highest ground in the arena uncontested for 10 seconds. That's what's displayed in the scoring explanation @2:55 in this video.

Also, the no locks round 1-2 is a new rule, as most of the fights in November had round 1 submissions.

In addition, you can actually influence the madness. Voting to give the team a numerical advantage, tie enemies special harness that limits movement, make it impossible to use two hands to arms... Finally, have a fight blindly! Now this is not a film with Statham, now a reality!

That could well be it. I've read it again and it says "за удержание командой фигуры в течение 10 секунд "
"For team control of the figura for 10 seconds". They use a couple of different words for the place where they're fighting, and I guess figura must be one of them.
